(a)
Interpretation:
The direction in which the equilibrium for the given reaction will shift with an increase in the volume of the container is to be predicted.
Concept Introduction:
Le-Chatelier principle states that the when a dynamic equilibrium is subjected to a change, the equilibrium moves in a direction so as to counteract that change. If the volume of the container increases, the pressure of the container decreases. The equilibrium will shift in the direction in order to decrease the pressure and vice versa.
(b)
Interpretation:
The direction in which the equilibrium for the given reaction will shift with an increase in the volume of the container is to be predicted.

- Phosphorus pentachloride gives an equilibrium mixture of PCl5 PCl3, and Cl2 when heated. PCl5(g)PCl3(g)+Cl2(g) A 1.00-L vessel contains an unknown amount of PCl5 and 0.020 mol each of PCl3 and Cl2 at equilibrium at 250C. How many moles of PCl5 are in the vessel if Kc for this reaction is 0.0415 at 250C?arrow_forwardSynthesis gas (a mixture of CO and H2) is increased in the concentration of hydrogen by passing it with steam over a catalyst. This is the so-called watergas shift reaction. Some of the CO is converted to CO2, which can be removed: CO(g)+H2O(g)CO2(g)+H2(g) Suppose you start with a gaseous mixture containing 1.00 mol CO and 1.00 mol H2O. When equilibrium is reached at 1000C, the mixture contains 0.43 mol H2. What is the molar composition of the equilibrium mixture?arrow_forwardPhosphorus pentachloride, PCl5, decomposes when heated. PCl5(g)PCl3(g)+Cl2(g) If the initial concentration of PCl5 is 1.00 mol/L, what is the equilibrium composition of the gaseous mixture at 160C? The equilibrium constant Kc at 160C is 0.0211.arrow_forward
- What is the equilibrium composition of a reaction mixture if you start with 0.500 mol each of H2 and I2 in a 1.0-L vessel? The reaction is H2(g)+I2(g)2HI(g)Kc=49.7at458Carrow_forwardHydrogen sulfide, a colorless gas with a foul odor, dissociates on heating: 2H2S(g)2H2(g)+S2(g) When 0.100 mol H2S was put into a 10.0-L vessel and heated to 1132C, it gave an equilibrium mixture containing 0.0285 mol H2.

SO2is added. b. SO3is removed. c. The volume is decreased. d. The temperature is decreased.arrow_forward
- Carbon monoxide and hydrogen react in the presence of a catalyst to form methanol, CH3OH: CO(g)+2H2(g)CH3OH(g) An equilibrium mixture of these three substances is suddenly compressed so that the concentrations of all substances initially double. In what direction does the reaction go as a new equilibrium is attained?arrow_forwardThe Mond process for purifying nickel involves the formation of nickel tetracarbonyl, Ni(CO)4, a volatile liquid, from nickel metal and carbon monoxide. Carbon monoxide is passed over impure nickel to form nickel carbonyl vapor, which, when healed, decomposes and deposits pure nickel. Ni(s)+4CO(g)Ni(CO)4(g) Write the expression for Kc for this reaction.arrow_forwardConsider the following hypothetical reactions. The equilibrium constants K given for each reaction are defined in terms of a concentration unit of molecules per liter. A(g)B(g)K=2X(g)2Y(g)K=62C(g)D(g)K=1 Assume that the reactions have reached equilibrium. Match each of these reactions with one of the containers I to IV (each of which has a volume of 1 L).
